Summary:

The Sonora Union High district operates three public high schools serving grades 9-12 in the Sonora area, with a total enrollment of nearly 1,000 students, featuring one large comprehensive high school and two much smaller alternative programs.

Sonora High is the district's primary and highest-performing school, enrolling about 89% of district students, achieving above-average scores in English and Science, and boasting an excellent 96.4% graduation rate with a low dropout rate. In contrast, Theodore Bird High and Dario Cassina High are significantly smaller, share an address, and serve student populations with higher economic need, showing much lower academic proficiency but surprisingly high graduation rates at Theodore Bird.

Key challenges across the district include concerning chronic absenteeism, especially at the two smaller schools where rates exceed 60%, and mathematics performance that lags behind the state average at all three schools. While the district's overall graduation rate is strong, the wide performance gap between the main high school and the alternative programs significantly impacts the district's overall state ranking.
